I had bought a hdmi cable 20m in the purpose of the recessed into the wall for my home theater room. I test the cable before: 1080i resolution obtained. Once the construction finished my display is not only low resolution (and m ... in!). Before throwing my video projector full hd 3D coffee machine & Co 1000 by the window, I try this ... and miracle! It works (1080i also I do not know if I can have 1080p)! Thank you a small package!
